The objective of the present invention is to allow reagents to be mixed, stirred, purified, reacted and the like using a cartridge sealed from outside air. Chambers (38) for reagents transported as liquids and chambers (39) for the destination of transported liquids are provided inside a cartridge (1) sealed from outside air, and these are connected by liquid transport channels. A groove is carved into a cartridge main body (30), and a membrane (31), which is an elastic body, is applied over the same to form a liquid transport channel (36).A liquid is made to move in the channel by changes in the volume of the liquid transport channel (36) caused by air pressure applied to the membrane (31). A valve function is given to the inlet of each chamber, and the liquid inside is moved in any direction in conjunction with the changes in the liquid transport channel. Thus, liquid can be transported within the cartridge, which is sealed from outside air, and reagents can be mixed and stirred, purified, reacted and the like inside the cartridge. In addition, the cost of the cartridges themselves can be held down by the valve structure being provided in a holder (2) into which cartridges are set and not providing the same within the cartridge. |
